>> jennifer, you said you're looking north of the building. in other words, you're south of the building. is that right? >> correct. >> because we're looking at a picture that is looking at the north side of the building. >> i'm on the exact opposite side. >> and it appears that is where the largest hole is and, again, as you mentioned correctly, towards the top of the building but on the north side. then on the, what i think is the west side of the building, we can also see some holes there that could have been from damage once the impact occurred. again, we've been told that this is a plane. we don't have confirmation on that, but there is an enormous hole in the north side of that building. >> jennir, can you tell us a little more what you heard when you heard this explosion? describe it for us? >> absolutely. when i walked out of the subway, i looked at the twin towers, because, i mean, i just always look up there, and right when i looked up, there was a boom. it wasn't -- it wasn'that loud. like, it wasn't huge. however, it was unbelievable was the amount of fire.
